When a material is loaded under stress, the accumulating elastic energy eventually sets off dissipative processes, such as plastic deformation. These processes are generally mediated by dislocation ...

Even with the weight of worlds on its shoulders, diamond resolutely refuses to buckle under the pressure. Thanks to the highest-pressure X-ray diffraction experiments ever reported, researchers have ...

Under extreme conditions, gold rearranges its atoms and forms a previously unknown structure. And when the pressures were pushed to the equivalent of those at the center of the Earth, the gold got ...

Out of the many boron nitride (BN) structural forms, cubic-BN (c-BN) nanodots (NDs) offer the potential for a variety of new opportunities across a plethora of applications. Until now, experimental ...

Ice-crystal halo: haloes such as the one seen here (photographed in Quebec City) are produced when light from the Sun or Moon interacts with ice crystals suspended in the atmosphere. Scheiner’s halo ...

Carbon is in group IV A of the periodic table with atomic number 6, an atomic weight of 12.011, and a density of 2.26. It melts at 3727 C. The stable form of carbon at room temperature is Graphite ...

Crystal Structure of Cubic Garnet-Type (IMAGE) Toyohashi University of Technology (TUT) Caption Fig. 1 shows crystal structure of cubic garnet-type Li7La3Zr2O12 (LLZO, left) and temperature dependence ...

Engineering ceramics such as zirconia (ZrO 2), alumina (Al 2 O 3), silicon nitride (Si 3 N 4), silicon carbide (SiC) etc. have been used more frequently in engineering applications as engineers and ...

When high-velocity asteroids land on Earth, they can form a meteor impact crater. Such collisions have occurred throughout Earth's history and still occur on other planetary bodies today. While most ...
